Just FYI, the CTA board voted to make the fare increases official yesterday.
They did make one change to the original proposal: CTA riders who use a Chicago Card or Chicago Card Plus will be exempt from the extra $2.75 charge at O'Hare until July 1, 2013. Transit Card users will have to pay the extra charge ($2.25 regular fare plus $2.75 O'Hare surcharge for a total of $5).
For those who don't know, a Transit Card is the flexible plastic card with the magnetic stripe that the Transit Card and Express Vending Machines at the 'L' station dispense. A Chicago Card is a hard plastic touch card with an RFID chip inside. Chicago Cards cannot be purchased at the airport, but if you already have one, it can be recharged at the Transit Card and Express Vending Machines.
"Express Vending Machines" are the Transit Card machines found in a few train stations that only accept credit cards. They work only in multiples of $5. They are often out of order. "Transit Card Vending Machines" are in all train stations, accept cash only, and do not make change.
